Using Aristotle API for AI-Assisted Theorem Proving in Lean 4: A Formalisation Case Study of the Grasshopper Problem
Case study formalizes an AI-generated proof attempt for the Grasshopper problem in Lean 4, verifying four helper lemmas on maximality and adjacent swaps but leaving the main theorem unresolved due to missing global counting argument.
